Modern smartphones Huawei have an impressive amount of built-in storage, but over time, even 256 or 512 GB can be filled to capacity. Users often encounter annoying notifications that data is full, which leads to system slowdown and the inability to install new updates. Understanding how to properly manage space is a key skill for any owner of a device based on internal memory is full, which causes the system to slow down and make it impossible to install new updates. Understanding how to manage space wisely is a key skill for any owner of a device based on EMUI or HarmonyOS.
The cleaning process does not require complex technical knowledge or connection to a computer. In most cases, it is enough to use the built-in optimization tools that the developers have provided specifically for these purposes. However, in order to achieve maximum results, it is necessary to take a comprehensive approach to the issue, affecting not only the system cache, but also user data, which takes up the lion's share of space.
In this article we will analyze in detail all the available methods for freeing up space: from basic cleaning through settings to manually deleting forgotten files in hidden folders. You will learn to distinguish important system data from digital garbage and will be able to return your gadget to its former operating speed without losing valuable information.
Using the built-in phone manager
The easiest and safest way to start fighting for free space is to use the standard “Phone Manager” (or “Optimizer”) application. This tool is pre-installed on all brand devices and automatically scans the system for temporary files, remnants of deleted applications and duplicates. Starting the scan takes only a few seconds, after which the system offers to clean up the found garbage.
To access the deep cleaning functions, you need to go to the Cleaning section inside the application. Here, algorithms analyze the storage structure and sort data into categories: large files, unused applications, similar photos. It is important to carefully review the proposed list before confirming the deletion, as automation can sometimes mark important documents as unnecessary.
⚠️ Attention: The “Deep Cleaning” function may suggest deleting files from the folderDownloadorDocuments. Be sure to check the contents of these directories manually so as not to erase work contracts or personal photos.
In addition to removing garbage, the phone manager allows you to control the startup of applications, which indirectly affects performance, but not the amount of memory. Regular use of this tool at least once a week will help keep the system clean and prevent critical disk filling.
Set up automatic cleaning in the phone manager settings so that the device itself deletes temporary files once a week without your participation.
The built-in manager is the safest tool for beginners, as it protects system files from accidental deletion.
Memory analysis by category in settings
If automatic cleaning does not give the desired result, you need to proceed to manual storage analysis. There are detailed statistics in the Android settings menu showing which types of data are taking up the most space. Follow the path Settings → Memoryto see a visualization of the distribution of space between applications, images, videos, audio and system files.
Most often, the largest volume is occupied by multimedia files and messenger data. The “Images and Videos” section can swell to tens of gigabytes if you actively use the camera or save content from social networks. The system allows you to sort files by size, which helps you quickly find heavy videos that can be moved to your computer or the cloud.
Particular attention should be paid to the “Other” section. Archives, documents, and offline map data are often hidden in this category. Sometimes system update files that were not automatically deleted after successful installation end up here. Manually checking this category can free up several gigabytes of free space.
Analysis by category gives a clear understanding of where the space goes. This allows you to make informed decisions: whether to delete old videos, compress photos, or perhaps transfer some data to an external drive. Without this step, cleaning turns into a chaotic deletion of files at random.
Cleaning the cache and data of specific applications
Applications during operation accumulate a huge amount of temporary data, known as cache. Social networks, browsers, and video services save thumbnails, viewed pages, and buffered videos to speed up loading times. Over time, the cache size of one application, for example YouTube or Instagram, can reach several gigabytes.
To clear the cache of a specific application, go to Settings → Applications → Applications. Select the desired app from the list and click on “Memory”. Here you will see two buttons: “Clear cache” and “Erase data”. The first deletes only temporary files without affecting your logins and settings. The second resets the application to its factory state, deleting all accounts and local data.
- 🗑️ Browser cache: Can take up to 1-2 GB, safely deleted through browser or system settings.
- 💬 Messenger data: Telegram and WhatsApp store a history of media files, which is best cleared through the settings of the application itself.
- 🎮 Game cache: Heavy games download additional resources that can be deleted if you haven’t played for a long time.
- 🛒 Marketplaces: Applications like Ozon or Wildberries cache product images, taking up space in vain.
Regularly clearing the cache of heavy applications is an effective way to free up space without deleting the apps themselves. However, it is worth remembering that after clearing the cache, applications may take a little longer to load when first launched, since they will have to download the necessary resources from the network again.
What is the difference between clearing the cache and erasing data?
Clearing the cache deletes only temporary files (pictures, scripts), speeding up work, but without affecting your settings. Erasing data completely removes the application from memory and resets it to the “just installed” state, requiring you to log in to your account again.
Managing files for WhatsApp and Telegram messengers
Messengers are the main “eaters” of memory on modern smartphones. By default, WhatsApp and Telegram automatically save all received photos, videos and documents to internal memory. If you are a member of dozens of chats and channels, this stream of content can quietly fill up all the free space in a couple of months.
The situation is solved most elegantly thanks to the built-in cloud storage function. Go to Telegram the situation is solved most elegantly thanks to the built-in cloud storage function. Go to Settings → Data and memory → Memory usage. Here you can set a cache storage limit (for example, 500 MB) and configure the automatic cleaning period (3 days, 1 week, 1 month). This will allow you to use all the functions of the messenger without filling your phone's memory with old memes and videos.
With WhatsApp the situation is more complicated, since it stores media files locally. You need to go to the chat settings of a specific interlocutor or group and disable “Media Visibility” or autoloading. In addition, inside the settings of the application itself there is a “Storage” section where you can delete the largest files, sorted by size. It often turns out that old videos from work chats take up gigabytes of space.
⚠️ Attention: Before mass clearing media files in messengers, make sure that important documents and photos are saved in another location. Deleting them from the phone's memory can lead to loss of access to them, especially in WhatsApp.
Manual sorting of files inside instant messengers allows you to specifically remove unnecessary content. For example, you can delete all the videos sent a year ago, while leaving text messages and important documents untouched. This approach provides a balance between free space and preserving communication history.
☑️ Setting up messengers to save space
Transfer data to a memory card and to the cloud
If the internal memory is critically full, then delete If you don’t want anything, the optimal solution would be to transfer data to external media. Most models Huawei support format memory cards Nano Memory (NM) or standard microSD. This allows you to move photos, videos, music and documents, freeing up valuable internal space for running your system and applications.
To transfer files, use the “Files” application. Select the desired media files, press the menu and select “Move” or “Copy”, specifying your memory card as the quality. Some applications, such as the camera, can be configured to save photos directly to the SD card through the settings of the camera application itself.
An alternative to a physical card is cloud storage. Services like Google Photos, Yandex.Disk or proprietary Huawei Cloud allow you to upload photos and videos to the Internet, and then delete them from the device. The “Free up space” function in Google Photos automatically deletes from your phone those pictures that have already been successfully uploaded to the cloud.
| Data type | Recommended storage location | Advantages |
|---|---|---|
| Photo and Video | Cloud or SD card | Quick access, protection against loss if the phone breaks down |
| Music | SD card | Save traffic, high quality without compression |
| Documents | Cloud | Access from any device, version synchronization |
| Applications | Internal memory | Maximum operating speed, stability |
Using a hybrid data storage scheme - when some files are in the cloud, and some on the card - is the most rational approach. This protects the user from filling up the internal memory and provides access to archives even when the phone is not at hand.
Use the “Smart Album Folder” feature in the Gallery to quickly find screenshots and memes that often take up a lot of space but have no value.
Removing unnecessary applications and system updates
Over time, a zoo of applications accumulate on your smartphone that you no longer use. Games you played a month ago, food delivery services, or photo editing apps may quietly take up space in the background. Regular audit of installed software is a mandatory procedure to maintain the cleanliness of the system.
Go to the section Settings → Applications and sort the list by size or by date of last use. Android 10 and above often highlight applications that have not been launched for a long time. Ruthlessly remove what you don't use. If you rarely need the application, consider using its web version through a browser, which will save space.
System update files deserve special attention. Sometimes, after a successful firmware update, an installation package remains in memory that is no longer needed. Usually the system removes it itself, but if it crashes it can get stuck. Searching for files with the extension .zip or folders with the name update in the root directory can help find such “tails”.
⚠️ Attention: Do not delete system applications whose names contain the words “System”, “Android”, “Services” or “Framework”, even if they take up space. This can lead to unstable operation of the phone or endless rebooting.
It is also worth checking the folder Download (Downloads). Browsers and instant messengers often save APK installation files there that were used to manually install apps. These files are no longer needed and take up space as dead weight.
Is it possible to transfer applications to a memory card on Huawei?
On modern versions of EMUI and HarmonyOS, the function of transferring applications to an SD card is often missing or limited. The system strives to keep applications on fast internal storage for stability. You can transfer only some data or media files.
Frequently asked questions (FAQ)
Why is the space not freed up after deleting files?
This is a common problem associated with the operation of the Recycle Bin. In the Gallery and Files app, deleted items first go to the Trash, where they are kept for 30 days. To free up space instantly, you need to go to the trash and empty it completely.
Is it safe to delete the Android folder on a memory card?
The folder Android contains application data (cache, obb files of games). If it is on the internal memory, do not touch it manually. If on a memory card, deleting will free up space, but games and applications may reset settings or require re-downloading data.
How to find out what exactly is taking up the most space?
Use the built-in application "Phone Manager" → "Cleanup" or go to Settings → Memory. There is a detailed chart showing the distribution of space by category: applications, images, videos, audio, etc.
Can a virus occupy memory on Huawei?
Yes, malware can masquerade as system processes and generate junk files. If the memory fills up by itself immediately after cleaning, check your phone with an antivirus through Phone Manager and remove suspicious applications that were recently installed.
What to do if the system writes “Memory is full”, but the files are deleted?
Try to restart the device. Sometimes file indexing is delayed, and the system does not immediately see the free space. Also check the cache of the Media Storage application in the application settings, displaying system processes.
